Answer:
import java.util.Scanner;
public class num2 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int count =0;
int total = 0;
System.out.println("Enter the numbers");
int num = in.nextInt();
while(num!=-1){
total = total+num;
count++;
System.out.println("Enter the next number");
num = in.nextInt();
}
//Compute the average
double average = (double) total/count;
//Outputs
System.out.println("Total count of numbers entered "+(count));
System.out.println("Sum of the numbers "+total);
System.out.printf("Average is %.2f ",average);
}
}
Explanation:
- Using java programming language
- Import scanner class to receive user input
- declare variables count and total and initialize to zero
- Prompt user to enter numbers
- Use a while statement with the condition while(num!=-1)
- Within the while body keep prompting user to enter a number, increase count and update total
- when -1 is entered the loop breaks and average is calculated
- Use printf() method to print average to 2 decimal places.

Explanation:
Users and system managers/administrators do not necessarily see the use of security investments, because there is no security breach or security failure to the system.
When security infrastructures are in place, it is to prevent or at least reduce the possibility of devaluation, modification, corruption, destruction or deletion, disruption, disclosure, use, and inappropriate or unauthorized access. So, if any of these breaches do not occur, system managers and users perceive little benefits from security investments.
